Practical Consequences of Electromagnetic Interference in Wireless Applications

The use of wireless applications . is continuously increasing in the society. Together with the overall increased use of electronics in general, the total electromagnetic environment is increasing around wireless systems. The effect of interference does not always appear as interruption in communication, but can appear as more or less gradually performance degradation for the user. In this article, some of these interference consequences are discussed and examplified.

EMC in Product Development (Part 7)

This article . is a part of a series of texts that will deal with the EMC challenge in terms of project management and the practical EMC activities at different stages in the project flow.
Different companies all have their own way of describing their project flow, so to keep it simple we will use the labels as given in Figure 1. We can call it a generic project flow. The picture only describes the basic outline of the work packages. These articles will describe the actual practical work we want to do in the project to “make EMC work” in a time- and cost-efficient way. Each part of our series will fill in the details for each part piece by piece. This is the 7th part – The aftermath – in our process.

Measuring wireless performance of vehicles

Wireless connectivity . in cars is becoming more and more important. The functionality of the cars depends on a reliable wireless communication, e.g., for safety systems, infotainment, traffic warnings and updates of software and maps. To ensure that the desired and required wireless communication is achieved, extensive testing needs to be performed. Today a lot of the testing is done with drive-tests out in the field. However, this is both expensive and can only be done late in the development process, which makes it hard to modify the product.

Report from EMC Europe 2019

EMC Europe . International Symposium on Electromagnetic Compatibility was arranged the 2 – 6 September in Barcelona Spain. It was locally organized by Universitat Politècnica de Catalunya, Campus Nord. EMC Europe is the major European conference on Electromagnetic Compatibility and covers a wide area of topics within EMC. As usual, the conference had tutorials, workshops, poster sessions and oral sessions. High quality scientific and engineering papers were presented in a variety of themes within EMC.

EMC Challenges and Solar Panel Systems

The use of . solar panel systems is rapidly increasing and some of these systems are co-located in the vicinity of wireless systems. Measurements have shown that the radiated emission from solar panel electronics can reach considerable levels, in some cases even above CISPR 22 Class B. Here, examples of interference impact is discussed for two examples of wireless applications, air traffic control communications (ATCC) and High-Frequency (HF) communications. The overall conclusion is that co-location of solar panel systems with wireless communications, must be carefully analyzed not to create interference problems.

Why electricity kills bearings – new insights

An article in Electronic Environment . 2017/2, is about the fundamental failure mechanisms (capacitive, inductive coupling and frame voltage) that cause EDM (Electric Discharge Machining aka Bearing Currents or Electric Erosion) in bearings. This article expands on the theme and shows why “The Simple Explanation”, The Mathematical Models and the Real World view on EDM differ, both in nature and in practical use. It also adds a couple of new insights that are becoming more and more valid with the widespread use of Frequency Inverters and loads with higher-than-normal capacitance to ground.
